After injection molding (SC) and severe plastic deformation (SPD) by hot rolling and equal channel angular pressing, a microstructure with reduced average grain size is formed.
Plastic deformation
It was found that at t° 4.2-25°K plastic deformation becomes unstable (stepwise). With grain refinement, the strain hardening rate of the metal decreases, but its plasticity (strain to fracture) increases due to texture. The strain rate sensitivity at T ≤ 100°K is independent of the microstructure and is determined by the intersection of dislocations "forest". With increasing temperature in the interval 150-295°K the velocity sensitivity increases due to the activation of dynamic recoil and the increasing role of diffusion processes in the plastic deformation of micrograined materials.
Strengthening
Alloy was irradiated with a powerful ion beam with an energy density of 3.4 J/cm2, under dry friction conditions. The surface morphology, composition and structure of the irradiated magnesium alloy were investigated by electron microanalysis (ERMA) and X-ray diffraction (XRD). The results showed that irradiation of MIP leads to an increase in surface microhardness and a decrease in the friction coefficient and wear rate. The MIP treatment produced areas of increased oxygen diffusion, resulting in surface layer densification and protective films on the wear track surface.
